Because the circuit is operated with a 3v battery while most of the parts are rated at much higher levels.
Electric mosquito swatter voltage.

Times the rms nominal ac mains voltage 340 vdc.
The grid of the flyswatter is electrically charged to a voltage of between 500 and 2 750 volts v activated by pressing and holding a button.
Buy electric mosquito swatter usb rechargeable with led light 3 layers safety mesh protection fly swatter for indoor and outdoor pest control white blue online on amazon ae at best prices.
When the electrically conductive body of a fly nearly bridges the gap between electrodes a spark jumps through the fly.
When the electrically conductive body of a fly nearly bridges the gap between electrodes a spark jumps through the fly.
Depending where in the ac cycle the device is unplugged the charge on the cap could be as much as 1 414.
Faults in a mosquito swatter bat circuit board can be very rare.
The resistor across the 240 vac mains series cap c1 serves to drain residual charge to prevent possibility of a small shock.
This voltage is then fed over the net of the device and is used to roast or electrocute any bug that may happen to come across the lines.
This stepped up 1500v is then terminated to the mosquito racket net which now becomes armed with this high voltage and when ever a mosquito tries to get past the racket net it instantly gets electrocuted through this high voltage discharge from the ppc capacitor.

The circuit inside these magnificent devices though is complex and involves several voltage booster stages which is finally stepped up to several thousand volts.
Outer nickel plated stainless steel mesh and inner layer aluminum mesh design will not leak electricity and is resistant to deformation.
